Novel Gpr39 Agonists: Correlation Of Binding Affinity Using Label-Free Back-Scattering Interferometry With Potency In Functional Assays
Daniel Brown (1), Niklas Larsson (2), Ola Fjellström (3), Anders Johansson (3), Sara Lundqvist (2), Johan Brengdahl (2), and Richard J. Isaacs (1)

We describe the application of back-scattering interferometry (BSI) to the characterization of small molecule ligand binding to human GPR39 (a GPCR targeted for type-2 diabetes therapy) overexpressed in crude membrane fractions in free solution, including how BSI-derived affinity and functional assay-derived potency correlate for compounds of varying scaffolds.

PRESEPSIN, A SOLUBLE CD14-SUBTYPE, A POSSIBLE NEW BIOMARKER INCREASES IN SEPTIC PATIENTS’ PLASMA FROM PEDIATRIC DEPARTMENT.
Hayato YAMAGUCHI1), Satoshi KIMURA1), Seiji FUKUOKA1), Emiko NAKAMA1), Hideyasu OTO2), Makoto INOUE2), Takashi SOGA2), Shigetaka KITAZAWA2), Yoh UMEDA2)

Increased plasma concentration of soluble CD14-subtype (presepsin) was observed in pediatric patients with bacteremia. Presepsin could be a possible biomarker of sepsis in pediatric patients, however, their reference interval in children could be lower than that of adults. More studies with larger number of samples are required to confirm the result.

A Novel Approach Toward Microfluidic Drug Metabolite Synthesis – Electrosynthetic Methodology Simulating Cytochrome (CYP450) Oxidation
Romain Stalder, Gregory P. Roth and Philip Podmore

A novel microfluidic technology and electrochemical synthesis method is demonstrated for the efficient generation of known drug metabolites. These metabolites are typically generated on first pass hepatic oxidation in vivo. The FLUX Module, a new microfluidic electrochemical cell manufactured by Syrris Ltd., has been employed to generate the metabolites of five commercial drugs: Tolbutamide, Chlorpromazine, Diclofenac, Primidone and Albendazole.

Exploring the Therapeutic Potential of a Peptide Derived from a Poxviral Immune Evasion Protein
Dylan Lawless

•9R-VIPER is an effective at TLR4 and TLR2 signal inhibition than VIPER.
•The structure of 9R-VIPER and the mutant peptide L6AE10A were investigated by NMR.
•Important structural information was uncovered and an explanation was found for the loss
of activity when important residues are changed.
